ATTACHMENT FOR AUTOMOBILE WHEELS Specification of Letters Patent.

Patented Mar. 21, 1922.

To all whom t may concern.'

Be it known that ABRAHAM S. Mnenorr, a citizen oli the UnitedStates, and resident of 188 St. Nicholas Avenue, in the city and county of New York and State oli' New York, has invented certain new and useful Improvements in Attachments for nutomobile Vllheels7 'of whichv the following is a specification.

VMy invention relates to improvements in means for readily removing the tire and tire rim of automobile and the like tirel'lcaring wheels.

Among the objects of this invention are the following: to provide an attachment for automobile wheels of the character and purpose described herein and in' my prior application which shallbe readily adaptable for use with an automobile wheel, the telly ol which is provided with the usual metal band curved to receive vthe lower curved shoulder of the demountable rim; to provide lsuitable means for preventing relative motion between the metal band oft the telly or the Ytelly itself` and the demountable rim; to provide improved locking means for lockine; the plate which is an embodiment of this invention to the wheel, which means shall be simple in constructiom more ellicient, easy' and quick in its operation, and inexpensive to make; and to provide an embodiment of the invention described in my 'prior application which shall be cheaper and simpler in construction, and more eflicient and effective in its operation, and better adaptable in practice for the purposes set iorth herein and in my prior application.

Other objects and advantagesV of this invention will appear from. the detailed description and the features oi? novelty will be particularly pointed out in the claims.

Certain features herein shown and described are shown, described and claimed in my co-pendingapplication, Serial No. 274;; 587, liled in the United States a,Patent Oiiice February 1st, 1919, and accordingly arenot claimed herein. f l

With the above exception, the invention accordingly consists'in the ieatureso construction, combinations of elements and afrranpfement of parts which will be exemplified in the apparatus hereinafter described and the scope of the application of which will be indicated in the following claims.

In the drawing,

Fig. 6 is a broken away vertical section showing,1 particularly the upper and lower portions of the wheel and the means for preventing relative motion between the telly and the demountable rim,

Fig. 7 is detailed sectional view taken alongr line 7-7 of Fig, 6,

Fig. 8 is a perspective view of one lorm ot tool specially adapted `for the manipulation of the plate.

Referring in ,detail to the drawing, lO indicates the automobile tire and 1l. the deinountable rim. The 'telly l2 on the wheel is provided with the usual metal band 13 curved to receive the lower, curved as at lil. portion 15 of Vthe demountable rim. The continuous plate 16 is for the most part similar in construction to the plate (designated by 13 in my'prior application) referred to herein. diiierences are to be noted:

'The vpresent plate or ringlll has its upper portion 1'? shaped to accommodate the lower curved portion 1S oi the demountablc rim and has a lower fiat portion 19 adapted to be substantially parallel to the face oi the folly.

This upper portion '17 and the lower portion 18 are adapted to irictionally engage along' a narrow surface, making substantially a line contact. rllhis constructionA o'i` the plate to provide the curved portion and fiat portion as described is highly advantageous in that when the plate is secured :in position as 'hereinafter described, contact between the demountable rim and the plate made onlyalong a portion of the latter, and because of the ycorrespondence in contour, it is possible to make a tight holdinn` fit without having" all of the curved surlace oi? the plate contact with the demonntable rima In the drawing, it willbe noted However, the following the plate and the rim thus takes place at the point of greatest strength and at the same tinie only along this circular line. In this way? that is by forming` the flanged plate as described, l accomplish a strong tight hold between the rim and the plate and yet the latter contacts with the rim only along a line of its surface tlius preventing the metal plate `frein sticking to the rim due to oxidation or rust'. The means of attaching and removing the plate 16 con sists in the spaced slots 20 cut in the plate, these slots terminating in an venlarged opening 21 larger than the head 22 of the threaded bolts 23 whereby the plate is positively held against the demountable rim. lt will be understood that these bolts 23- pass through holes provided in the plate, the

metal band,V the felly and holdings,` plateor' washer 24 for the nut 24.` It willbe clear that whenlthe bolts lie in the extreme nai"- row end of the slots 20, the plate is positively heldon the wheel and againstV thev curved shouldei1 of the demountable rim along a continuous surface of contact provided by the curved portion 17 of the frame.

Between this portion 17 and the curved por` tion 14 on the metal band, the rim and tire are positively held 'on tlie-fellv It willbe noted that the plate 16 is held against the demountable rim to provide continuous frietional engagement `therewith and yet its flat portion 19 is spaced from the felly itselfy and not in contact therewith.Y The slotted portions of the plate are widened as at 25 to Lrive additional strength. To make the demountable rim loose en the felly it is simply necessary to give the Vplate 16 a partial rotation so that theplate moves relative to the bolts runtil the latter lie in theV enlarged openings 21 on the slot. 1f the locking means hereinafter described is unlocked, the plate may now be readily removed and the deniountable rim and tire ea sily taken olf and replaced.

The locking` means referred to above is provided for the purpose of preventing' the plate from slippingy when the wheel is in motion. This means consists of a bolt .26 held in a sleeve 27, V(preferably of brass to prevent rust). which passes through the felly. The bolt 26 is normally held in by the spring 28 held between the washer 29 Leidens so that the shank takes a position at right angles to thaty shown in Fig.` 4.v llVhen the Y partialfrotation is given to the plate the slot 34 permits relative motion between the boltand the plate7 and the latter may be removed. The locking means thus operate to help hold the plate in position, prevent rotation thereof and cooperate with the lioldine; means when the plate is to be removed.

The means for preventingf relative motion between the metal band andthe demountable rim are shown clearly in Fig. 6. These meansl consist simply in dowel pins 35 passing through perforations in the demount- `able rim, metal band, and felly on the upper part of the wheel:v On the lower part of the wheel the metal wedge 36 is weldedon to the demountable rim, and the shoulders 87 formed in the metal band enable the tapered metal piece to wedge in between` the metal band and the demountable rim.

.ine perforation 38, is made in the portion of the metal band disposed over the wedge so that grease in ay be applied to prevent rust.

3 shows one means for preventingthe contact surfaces of the plateand heads of the bolts from rusting This consists of a piece 39 of non-rustiiig` metal (preferably brass) secured in any suitable manner to the face of the plate 16 anddisposed over the slotted portion 2O thereof. This piece .39 is cut away to provide the slot 40 and the walls 41 on the slot which taper as indicated by the shading` to varyin thickness froma maximum at 42. y

Fig S'shows a: formV of tool. adaptable for manipulating the plate 16. lt consists sim- Y ply of a bar 43 having-at one endthereof a metal portion 44 cut away as at 45. A metal sleeve 46 is provided at the other end and a rubber capv 47 mounted thereon. To give the plate the desired partial rotation, the tool is simply applied to `the plate and lightly tapped or hammered.

Having thus described my invention, l claim as new and desire to secure by Letters Patent: i
